As a New York native, I'm always asked for restaurant ideas when friends come to town and one of my favorites places to recommend is Keens Steakhouse. The circa-1885 eatery and former “Pipe Club” (members included Teddy Roosevelt, Babe Ruth, Albert Einstein, and J.P. Morgan) maintains an authentic, "Old New York" vibe thanks to its dark, clubby interior decorated with vintage memorabilia and the world's largest collection of churchwarden pipes displayed across the ceiling. Dishes not to miss from their traditional American menu: Oysters Rockefeller, the Keen's creamed spinach, and their signature, man-sized mutton chop.
